This is a self-explaining freeware (also in english) for automatic correction of converging lines. See website for examples. It's easy to use and I've made fascinating experiences with it.

It seems to work great, just like if it was hand-made!
BTW Attila's image is a bit overcorrected on the right, because probably the software found it easier to correct the left line as closer to the edge. But the problem is because Attila did not shoot the image in perfect axis alignment with the centre.
Note however the total absence of geometrical distortion (barrel/pincushion) in the image. This is the Flek 4/20!!

The software is very clever, but to my professional eye the building has lost its slender proportions. It looks squat and ugly to me.
A degree of convergence is more pleasing to the eye than truly vertical lines. I would love to see how the program would handle a 100-storey skyscraper! |
